2 Claims.

This invention relates to a nose pad for an ophthalmic mounting.

Heretofore in nose pads when made of nonmetallic material have usually had a plate of metallic material sandwiched between the nonmetallic layers for stiffening the same and providing a means for attaching the nose pad in such position on the ophthalmic mounting as it is desired the same shall assume.

One of the objects of this invention is to provide a nose pad which will be of a simplified construction and thus less expensive to produce.

Another object of this invention is to provide a nose pad which will be sufficiently rigid so that the same will withstand the abuse to which it is normally put.

Another object of this invention is to provide a simple and quick means of attachment of a metal arm to the nose pad so that the pad may be mounted in position.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a perspective view of an ophthalmic mounting with my nose pad in position;

Figure 2 is a plan view of the rear surface of the nose pad prior to the assembly of the attaching arm in position;

Figure 3 is a sectional view on line 3-3 of Figure 2 Figure 4 is a sectional view of the attaching arm as positioned in the cup on the rear surface of the pad prior to rolling the edges of the cup inwardly;

Figure 5 is a sectional view showing the attaching arm as secured to the pad; and

Figure 6 is a perspective view of the pad and its attaching arm.

In proceeding with this invention, I form from non-metallic material a pad with a rearwardly extending wall forming a cup on the rear surface of the pad and then position in the cup an 2 for are shown at [5 for holding them in the desired position.

The nose pad is formed of a non-metallic material such as celluloid or some of the more recent resins and is of a shape such as may be desirable, as shown in Figure 2, and which is slightly curved to prevent a convex surface l5. Extending from the rear surface of the pad is a wall 16 which provides an enclosure or cup H.

An attaching arm is designated I8 and is provided with a head I 9 which will be of the same piece of material, this being of metal. The head I 9 is of a shape to snugly fit the cup I! and extend to the bottom surface 20 thereof. This head 19 is then placed in the cup and the edges of the wall I6 of the cup are rolled inwardly as at 2| over the rear surface of the head l9 so as to securely hold the head in position assembled with the plate or pad M. This attaching arm l8 may be bent as at 22 for assembly with the support 15 and further bent to hold it in place.

By this arrangement an attaching arm is very simply and eflectively held in position and may be assembled by the use of heat and pressure in a very inexpensive manner.

I claim:

1. A nose pad for an ophthalmic mounting comprising a plate of uniform thickness, a wall extending from the rear surface of said plate and inwardly from its periphery to provide a cup, the bottom wall of which is the thickness of the plate, said plate and cup being of thermoplastic material, and an attaching arm having a head of a size to be received in said cup and be retained therein by the wall being heated and deflected over said head.

2. A nose pad as in claim 1 wherein said plate and wall are of the same piece of non-metallic material.
